The FEM simulation of the Surface Acoustic Wave Delay Line based on the P-matrix model for Sensor Application

B. Panchal[1]
[1]NIT Calicut, Kerala, India

Since the last few decades, the researchers are focused on new sensor material and novel design structure with high performances. Today various technologies are available but SAW sensors are preferable because of its characteristics such as low cost, low power, lightweight, rugged, ... Read More

Static & Dynamic Analysis of Modular Cantilever Assembly

N. Pandey[1], R. Upasani[1], G. Bhoye[1], I. Jain[1]
[1]Raychem Innovation Center, India

Modular Cantilever supports two parallel tensioned cable structure i.e Contact wire, messenger wire and dropper for overhead catenary lines in railways. Its main function is to allow smooth movement of pantograph at desired speed and transfers vertical load, lateral forces and ... Read More

Bagpipe Chanter Vibration Analysis

M. Snaith[1]
[1]Xi Engineering Consultants Ltd., United Kingdom

This study investigates the use of COMSOL Multiphysics® to compare design variations in two different bagpipe chanters. Eigenfrequency analysis of material and geometry variations are simulated and compared to experimental results. The study suggests an increased damping ratio associated ... Read More

Modeling of Oil Spill Collection by Means of Devulcanised Crumb Rubber in COMSOL Multiphysics®.

V. Lapkovskis[1]
[1]Riga Technical University, Latvia

In current work, diffusion processes of oil spills through a thin layer of porous composite materials based on crumb rubber are investigated. Model setup includes a concept of layer built of crumb rubber particles (and composite constituents) distributed on the solid surface, gradually ... Read More

Acoustic Fluid Relocation for the Separation of Exosomes

L. Spigarelli[1], N. Vasile[2], D. Marchisio[1], C. Pirri[1], G. Canavese[1]
[1]Politecnico di Torino, Italy
[2]Italian Institute of Technology, Italy

The aim of the present work is to explore through the developed numerical model the separation of exosomes from a more complex mixture of particles i.e. red blood cells and white blood cells, through combined acoustofluidics and fluid relocation in a bulk acoustic wave microfluidic ... Read More

Rubber In-Ear Loudspeaker Resonator

A. Rodriguez[1]
[1]Xi Engineering Consultants Ltd., United Kingdom

The effects of an auxiliary resonating chamber in an in-ear headphone were simulated using COMSOL Multiphysics®. The auxiliary resonator consists of a rubber attachment that can be added to an in-ear loudspeaker. The purpose of the resonator is to increase the low frequency performance ... Read More

In-Air Fault Detection for Medical Ultrasonic Transducers

C. Chung[1], P. Verma[2]
[1]Xi Engineering Consultants Ltd., United Kingdom
[2]Sheffield Teaching Hospitals NHS Foundation Trust, United Kingdom

Ultrasound transducers are regularly used in medical clinics but their performance is known to deteriorate over time. Causes of this image quality degradation can include delamination between layers, physical breakage of components, short circuits and weakening crystals. Regular ... Read More

Measurement and FEA Simulation of the Electro-mechanical and Acoustic Response of an Of-the-shelf Open-type Piezoelectric Flexural Ultrasonic Transducer

S. Jackson[1]
[1]University of Bristol, United Kingdom

High power, air-coupled ultrasound has gained significant interest from the research community due to the rise in applications such as non-contact particle manipulation, haptic feedback, and sound steering. A growing number of researchers are utilizing transducers designed for proximity ... Read More

Mechanical and Thermal Effects of Focused Ultrasound on a Biological Tissue using COMSOL Multiphysics®, Three Different Approaches

N. El Sayed[1], A. Maurer[2], D. Enfrun[2], R. Rozsnyo[1]
[1]HES-SO Geneva, University of Applied Sciences and Arts Western Switzerland, Switzerland
[2]Kejako SA, Switzerland

Focused ultrasounds are used in many medical applications as a treatment: it is important to evaluate the induced effects of such a procedure to achieve a high accuracy while keeping the untargeted surrounding areas safe. In the present paper, COMSOL Multiphysics®, a simulation software ... Read More

Randomization to Tackle Mid-Frequency Acoustic Tones in Wind Turbines

B. Marmo[1]
[1]Xi Engineering Consultants, United Kingdom

Wind turbine towers can often become modal if matched closely in frequency with the excitation associated with rotating components in the drive train, such as gearboxes and generators. When these conditions are met, the modal response is greatly amplified due to the very low structural ... Read More
